1. A phase connection for electrically conductively connecting an inverter or converter to a busbar of an electric machine, comprising:
a housing part, further comprising:
a housing wall, the housing wall having a first side and a second side that is different from the first side; and
an opening extending between the first side and the second side being formed in the housing wall;
a load busbar which is routed through the opening and has a first connecting section which is routed beyond the first side and is formed at least in sections from soft-annealed copper and/or contains soft-annealed copper, the first connecting section further comprising:
a distal end section (DEA) on a side of the first connecting section facing away from the housing wall, the distal end section (DEA) having a fastening opening (BO);
a cap (KA), comprising an electrically conductive material, arranged on the distal end section such that the cap is adjacent to and in contact with at least two surfaces of the distal end section.
